In order to cleanup the main platform media directory, move Renesas
driver to its own directory.

Adopt the SPDX license identifier headers to ease license compliance
management. All files in the driver are licensed under the GPLv2+ except
for the vsp1_regs.h file which is licensed under the GPLv2. This is
likely an oversight, but fixing this requires contacting the copyright
owners and is out of scope for this patch.
While at it fix the file descriptions to match file names where copy and
paste error occurred.

The VSP2-DL instance (present in the H3 ES2.0 and M3-N SoCs) has two LIF
instances. Adapt the driver infrastructure to support multiple LIFs.
Support for multiple display pipelines will be added separately.
The change to the entity routing table removes the ability to connect
the LIF output to the HGO or HGT histogram generators. This feature is
only available on Gen2 hardware, isn't supported by the rest of the
driver, and has no known use case, so this isn't an issue.

The "Renesas Corporation" listed in the copyright notice doesn't exist.
Replace it with "Renesas Electronics Corporation" and update the
copyright years.

The VSP1 is a video processing engine that includes a blender, scalers,
filters and statistics computation. Configurable data path routing logic
allows ordering the internal blocks in a flexible way.
Due to the configurable nature of the pipeline the driver implements the
media controller API and doesn't use the V4L2 mem-to-mem framework, even
though the device usually operates in memory to memory mode.
Only the read pixel formatters, up/down scalers, write pixel formatters
and LCDC interface are supported at this stage.
